Stats really aren't an issue. I run 10437 when I want to play Destro seriously. It covers both a regular breakpoint and also one when under the effects of a 30% haste buff i.e. Bloodlust or Meta Gem. It REALLLLLLY isn't a huge deal. The DPS difference between 10436 and 10437 is probably less than 1%. I just like to have a healthy mix of both haste and crit and this has always been my preferred build.
